The Harbinger is an mTLS proxy designed to give AI agents a verifiable identity rather than relying on traditional API keys. This approach enhances security by enabling mutual TLS authentication for AI agent interactions.

AI-assisted summary based on the listed source.

Replacing API keys with identity-based authentication can reduce risks associated with key leakage and misuse. It also supports more secure and accountable AI agent communication in distributed systems.

Developers may have a new tool, API, or workflow change worth testing against their own stack.
